Hey everyone I’m wanting to see if any of you app have had this problem before and what you have found that was the problem. I just traded for this xj. That has a grounding issue. So I am blowing this 30 amp mini fuse in the distribution box. Off and on while driving the engine shuts off and I have to replace it. The heater core was bad in it and I had to replace the heater core last weekend. I installed it and hooked up my blower motor and I am blowing the 30 am fuse under the dash that. Controls the blower motor. I have figured out that the fuse panel underneath the dash is grounding as soon as I turn on the ignition. Even after I unplugged all the harnesses under the hood including the removing the Ecu. That it still is grounding as well as unplugging the fuel pump harness. Every time I turn the ignition on after everything is unplugged the fuse box underneath the dash still goes to ground? I haven’t touched the ignition itself yet.
